Subject: [PATCH 0/1] [GSOC] Use unsigned type for bit flags in commit-reach.c
MoumitaThe `flags` variable holds multiple bitwise flags (PARENT1, PARENT2, STALE),these flags are defined using (1u << N), so maybe there will be no issues if it is changed from `int` to `unsigned int`

Moumita[PATCH 1/1] commit-reach: use unsigned int for flags in paint_down_to_common()
The `flags` variable in `paint_down_to_common()` stores bitwise flags (PARENT1, PARENT2, and STALE), which are defined as `(1u << N)`. Since these are already unsigned values,`flags` can also be declared as `unsigned int` instead of `int`.

"This change will not break" is not a good reason to make the change, though, as not making that change will not break anything, either.
If you need to write something, say something that positively justifies the change, explaining readers why it is a good thing to do, and how the resulting code is _better_ than the original.
Thanks.
